运行在matlab平台，基于果蝇算法的最小而成支持向量机算法(Running on the MATLAB platform, the minimum support vector machine algorithm is based on the Drosophila algorithm.)

使用遗传算法对BP网络权值阈值进行优化，再用BP算法训练网络的代码，文本格式的(bp propoganda and genetic algorithm)

BCJR decoder，inputs are source bit,coded bit, and a priori, outputs are source bit and coded bit (a posteriori)(There s an array named table inside, describe the trellis, five column is: start state, destination state, source bit,coded bit 1,coded bit 2, respectively.)

用matlab仿真实现了25 kHz 带宽内同时传送总共48 kbit/s 的两路语音(每路速率9. 6 kbit/s) 和两路数据信息(速率分别为19. 2 kbit/s 和9. 6 kbit/s) , 仿真结果表明达到了较好的误码性能。并比较了4 种数字调制方式下O FDM 系统的误码性能。(using Matlab Simulation bandwidth of 25 kHz simultaneous transmission within a total of 48 kbit/s 2 Road Voice (rate of 9 per road. 6 kbit/s) and two road data information (rate of 19. 2 kbit/s and 9. 6 kbit/s), the simulation results indicate achieve a better BER. And comparison of four types of digital modulation mode O FDM system BER.)
